### validateMessages

Form provides [default verification error messages](https://github.com/react-component/field-form/blob/master/src/utils/messages.ts). You can modify the template by configuring `validateMessages` property. A common usage is to configure localization:

```jsx
const validateMessages = {
  required: "'${name}' is required!",
  // ...
};

<Form validateMessages={validateMessages} />;
```

Besides, [ConfigProvider](/components/config-provider/) also provides a global configuration scheme that allows for uniform configuration error notification templates:

```jsx
const validateMessages = {
  required: "'${name}' is Required!",
  // ...
};

<ConfigProvider form={{ validateMessages }}>
  <Form />
</ConfigProvider>;
```

## Form.Item

| Property | Description | Type | Default | Version |
| --- | --- | --- | --- | --- |

| dependencies | Set the dependency field. See [below](#dependencies) | [NamePath](#NamePath)\[] | - |  |
